COP-BUILDING MECHANISM FOR RING-SPINNING FRAMES.

SPECIFICATION forming part of Letters Patent No. 374,816, dated December13,1887.

Application filed March 10, 1884.

To all whom it may concern.-

Be it known that I, ALBERT BALL, of Glaremont, inthe county of Sullivanand State of New Hampshire, have invented a new and useful Improvementin Cop-Building Mechanisms for Ring-Spinning Frames; and I do herebydeclare that the following is a full and exact description of the same,reference being bad to the accompanying drawings, and to the letters ofreference marked thereon.

The purpose I have in view is the production of practical means forspinning on a spinning-frame a cop to resemble that upon themule-spindle, and to spin sucha cop by means more simple and lessexpensive and at the same time more effective than any hereto foreemployed. The means I propose are more simple, because complicatedmachinery heretofore employed is dispensed with, and less expensive infirst cost and in maintenance because of its simplicity, and moreeffective because there is no necessity for unusual care in running theframes or for a separate setting at each time of doffing. The means Ipropose will not only build up a cop shaped exactly like that of amule-spindle upon a cop-tube or similar bobbin, but by a ready andsimple adjustment the frame can spin a cop onthe conical-base bobbinusually employed for woof in ring-spinning frames.

The novelty in the mechanism hereinafter described consists,principally, in combining a particular sprocket-cam with the chain, in aparticular winding-drum with means for ad- 5 justing the length of thechain, and in other operative combinations of parts, all as more fullyhereinafter described, explained, and set forth in the claims.

For the better comprehension of my invention reference should be had tothe accompanying drawings, in which- Figure 1 is a side elevation of aportion of my ring-spinning frame with my improvements applied thereto;Fig. 2, an end elevation of the same; Fig. 3, a top plan view of thesame; Figs. 4 and 5, details of the winding-drum; Fig. 6, a longitudinalsection of the usual cop of the ring-spinning-frame; Fig.

7, a similar section of a mule-spindle cop, and

Serial No.123,619. (N0 modelfl which is conical from a point near itslarger end to the body, which is a slightly-tapering or anearly-uniformcylinder for the remainder 'of its length, and the yarn is wound upon itin successive layers of substantially the same length along the bobbinvcorresponding in shape with the slope of the conical base, as i shownin Fig. 6. c

What I desire is to dispense with the large conical base to the bobbinor tube, thereby incidentally saving weight and expense in the bobbins,enabling it to carry a greater length of thread, and therebyfacilitating and encour aging the spinning of warp or woof onfillingframes. In order that this cop may be built up upon such a tubeor bobbin so that the yarn will draw off smoothly and uniformly inweaving, it is essential, first, to build up its butt, which requires aconstantly regularly increasing length of each layer of yarn until therequisite slope is attained, as shown in Fig. 8, after which time thelength of each series is uniform until the cop is completed, as is shownin Fig. 7. The adj ustmentswhich will enable the traverse of the rail toproduce this build certainly and effectively constitute the essence ofmy invention, which is adapted to be applied to any of thespinning-frames for cotton filling or warp commonly used in this countryfor the last forty years. For instance, the supportingframe A, thespindle B, its ring C, the rail D, the guide-rod E, the rocker-lever F,the ratchet-wheel K and its pawl O, the cam Land its roller M, and shaftW and its support S, the driving-gear N, and

the lever X are well known, and the operation tion of the chain G, thesprocket-cam H, the

winding-drum I, the worm-gears J and Q, the handle P, and thescrew z,and in their combination and arrangement with each other and with theold and well-known portions of the spinning-frame.

The winding-drum, which is mounted on the lever X, is composed of twoparts, the grooved rim I having rotary movement on the hub I, which iskeyed or fastened in any suitable manner to the shaft I. This hub I isprovided with a face-plate, a, an arm or sleeve, 12, and a set-screw, 4,passing through said arm or sleeve, and which sets against the lug 5 onthe rim I. When the set screw is turned in one direction, the lug ismoved away from the arm and the drum is partly revolved in onedirection. By turning the set-screw the other way the drum is permittedto rotate in the other direction until the end of the sleeve or arm andthe side of the lug are in contact. The chain'G is attached to theperiphery of the drum I by any suitable device. The preferable manner offastening, however, and the one I have illustrated in the drawings, isby means of a screw, 2, to which the end of the chain is secured, andwhich continues down through the rim until it enters agroove on the hub,thus serving to lock the two against lateral but not against rotarymovements. The chain passes around the winding-drum and up 1 over asprocket-cam, H, journaled in a proper hanger, and preferably terminatesin a rod, G, an intermediate divided and threaded part of which is heldby a turn-buckle, 3, by means of which the rod and its connecting-chainmay be lengthened or shortened at will: At its outer end this rod isconnected with the counterbalanced rocker-lever F R in the usual way.

The drum I has connected with it a wormgear, J, upon which the worm Q,fixedupon the shaft Q of wheel K and adapted to be turned by the handleI, is operated by the handle P,so that the drum may be more or lessrotated at will and the chain drawn in or let out for the purpose ofadjustment before spinning.

The adjustment of the mechanism described forspinning cops like those ofmulespindles is effected in this wise: Ordinarily,when a cop has beendofled and the ring-rail brought down to its lowest or starting pointand the frame begins to spin the cop, the cam L is turned, thewinding-drum with its chain is raised up, the counterbalancing-weightcarries up the rail as far as the throw of this cam and of thewinding-drum and chain will permit, and on a further revolution of thiscam the rail follows its motion down. As it goes down, the pawl 0 takesone or more teeth of the ratchetwheel K, thereby, through the shaft Q ofwheel K, worm Q, and wheel J, unwinding the drum a little and lettingout the chain,so that the rail is not allowed to go down quite as far asits starting-point; but on its next upward traverse it goes a littlefarther than before, so that each traverse of the rail from thebeginning to the completion of the cop is through the samedistanceordinarily about one and seven-eighths inch.

In spinning the mule-cop in the method proposed by me it is necessary inthe first instance,in order to build up the butt,to have a traverse atthe beginning of about one and onefourth inch, starting a little higherup each time and making a little longer traverse each time until thebutt has been completed, and then the traverse will be uniform inlength, starting a little higher each time, until the cop is completed.In order to effect this constantlyvarying length of the traverse inbuilding up the butt of the cop, when the cop has been dofl'ed and thering-rail brought down to its lowest starting point and the cam L isturned and the winding-drum I, wit-h the chain G,is raisedup,thesprocket-cam H is turned so that its lowest point or shortestradius is upward, and the chain G is practically taken up by it theleast and so asto permit a traverse ofonly about one and one-quarterinch. When the rail is carried up as far as the throw of the cam L andthe effective length of the chain will permit, one layer of thread willbe woundv upon the bobbin or tube. The downward movement of the rail islimited in the usual way by the pawl O and the ratchet-wheel K and thelengthening thereby of the chain,'and thismovement downward of therail-stops at a point a little higher than the initial starting point;but by the unwinding of the chain the cam H is turned a little, so thatit presents a longer radius to the chain G, and the result is that thenext traverse of the rail is a little longer than the first and eachsucceeding traverse a little longer than the preceding until the cam His in such a position that it presents its longest radius to the chainand thereafter acts like a sheave, and the subsequent traverses of therail are of equal lengthsay one and seven-eighths inch--until the cop iscompleted.

In order to get the precise initial adjustment of the cam H with regardto the chain G, the chain is drawn in and the cam thereby changed in itsposition by means of the setscrew 4, which partially revolves the drumI, and drawn out by means of the turn-buckle 3, or vice versa, until theprecise desired position of the cam H in relation to the chain G isattained.

It will be understood that in use not more than one-half of theworking-face of the cam H is exposed to the chain. Therefore the same Icam may be constructed so as to give two different builds of a cop by adifferent construction of working faces, as shown in Fig. 1, where onecorner of the cam is shown as rounded and the other corner as sharp. Ifit position that the traverse of the rail will be of the same length allthe time that the cop is wound. \Vhen the mule-cop has been wound andthe operator is ready to doii', he winds up sequently brought back toits precise previous I claim as new therein, and desire initial positionand n0 setting is required. h
